RUBBER CORSET Filed Feb. 10, 1959 INVIENTOR. L/z/A/v flZ/AA AW 554 /74 United States Patent 2,993,490 RUBBER CORSET Juan Duarry Serra, Calle Rosellon 1, Barcelona, Spain Filed Feb. 10, 1959, Ser. N 792,440 4 Claims. (Cl. 128-421) The present invention relates to an improved rubber corset.

It is well known that the rubber corsets used nowadays are attended by the inconvenience that when worn they produce a sensation of cold and impede transpiration through the skin, which results in a disagreeable accumulation of perspiration. In order to avoid these disadvantages of rubber corsets, it has already been proposed to provide them with multiple drilled respiratory orifices and/ or line them or raise a nap on their interior surfaces with cotton, silk or other fibres. However, such improvements have not completely and satisfactory eliminated the mentioned inconvenience attendant on rubber corsets.

The rubber corset according to the present invention is essentially characterised by the fact that it consists of a rubber sheet whose inner surface is covered by a great number of protuberances of varied forms, sizes and heights, forming conjointly a kind of corallitic structure arranged over a thin film base, having numerous intercommunicating cavities which, by imprisoning air when the corset is applied by its interior surface to the skin, act as an efl'icient thermal insulator producing thereby an ageeable sensation of warmth.

The said film base, whose exterior surface is smooth, is provided with numerous pores that allow the free passage of the air, thus permitting the necessary cutaneous respiration when the corset is in position on the skin, thereby avoiding the troublesome formation of perspiration.

Another characteristic of the invention consists of the fact that the protuberances and the film base, both mentioned above, constitute a single body of the same material.

For purposes of clarity and better understanding of the invention, reference is made to the accompanying drawings, which represent by way of example one embodiment thereof. In these drawings:

FIGURE 1 represents a perspective view of a corset according to the invention, moulded in a single piece;

FIGURE 2 shows a section of the sheet material of which the mentioned corset is made, drawn to a greatly magnified scale;

FIGURE 3 shows a portion of the above mentioned sheet material seen from its interior surface and illustrated also on a greatly magnified scale.

In FIGURE 1 the corset shown is designated as a Whole by 1. This corset is composed of a rubber sheet whose inner surface 2 is covered by numerous protuberances 3 (FIGS. 2 and 3) of varied forms, sizes and heights, forming conjointly a kind of corallitic structure arranged over a film base 4, having numerous intercommunicating cavities 5. The corallitic structure, as clearly shown in FIG. 2, is characterized by the protuberances 3 being of random shape and having a plurality of cavities of substantial size distributed at random over their surfaces. The protuberances 3 have relatively small base connections to the film base 4 as compared to the upper portions of the protuberances 3. Thus it will be seen that the protuberances 3 are relatively flexible and are capable of bending about their base connections when the corset 1 is placed over the skin. The protuberances 3 and the film base 4 above mentioned constitute a single body of the same material, as may be clearly seen in the section shown 2,993,490 Patented July 25, 1961 in FIG. 2, and said film base is provided with numerous pores 6 that establish communication between the cavities 5 and the exterior smooth surface 7 of the corset.

When the corset 1 is applied over the skin by its inner surface 2, the cavities 5 formed by the protuberances 3 of corallitic structure imprison air, exercising in this way an efficient thermal insulation and producing an agreeable sensation of warmth. The pores 6, however, allow the free passage of air thus permitting the necessary cutaneous respiration and avoiding the troublesome formation of perspiration.

What I claim is:

1. An improved rubber corset, characterised by the fact that it consists of a rubber sheet whose inner surface is covered by a great number of protuberances of varied forms, sizes and heights, forming conjointly a kind of corallitic structure arranged over a thin rubber film base, said corallitic structure being characterized by said protuberances having relatively small base connections to said film base as compared to the upper portions of said protuberances and said protuberances being of random shape and having a plurality of cavities of substantial size distributed at random over their surfaces so that said corallitic structure has numerous intercommunicating cavities which, by imprisoning air when the corset is applied by its interior surface to the skin, act as an efiicient thermal insulator producing thereby an agreeable sensation of warmth.

2. An improved rubber corset according to claim 1, characterised by the fact that the said film base is provided with numerous pores that allow the free passage for the air, thus permitting the necessary cutaneous respiration when the corset is applied over the skin, thereby avoiding the troublesome formation of perspiration.

3. An improved rubber corset according to claim 1, characterised by the fact that the said protuberances and the said film base constitute a single body of the same material.

4. In the art of corsetry an improved undergarment for supporting and molding the figure characterized by the fact that it consists of a rubber sheet whose inner surface is covered by a great number of protuberances of varied forms, sizes and heights, forming conjointly a kind of corallitic structure arranged over a thin film base, said corallitic structure being characterized by said protuberances having relatively small base connections to said film base as compared to the upper portions of said protuberances and said protuberances being of random shape and having a plurality of cavities of substantial size distributed at random over their surfaces so that said corallitic structure has numerous inter-communicating cavities which, by imprisoning air when said undergarment is placed in wearing position with its said inner surface adjacent the skin, act as an efficient thermal insulator producing thereby an agreeable sensation of warmth, said film base being provided with numerous pores that allow the free passage for the air, thus permitting the necessary cutaneous respiration when the undergarment is applied over the skin, thereby avoiding the troublesome formation of perspiration, and said protuberances and said film base constituting a single body of the same material.
